To all whom it may concern: I

Be it known that I, Hamir TURNER, Sr.,. a subject of the King of Great Britain and Ireland, etc, residing at Glenelg, --in the State of South Australia, Commonwealth of Australia, have invented certain new and useful Improvements in Hose andother. Clamps; and -I do hereby declare the following to be a full, clear, and exact descri tion of the invention, such as will enab e others skilled in the art to which it appertains to'make and use the same.

This invention relates to an improved clam or binder of band or ring type for men g hose, for connecting an outer to an inner member, for'binding articles together, and for use in other ways. The

pressure on the article or articles to be fastened can be regulated, and the clamp is easy to apply and remove without using tools.

To regulate m clamp I use a screw bolt which has also t e function of a lever,-and contraction of or com ression b the band can be thereby eifecte and the orce of the clamp grip may be varied to produce the joint desired.

I provide an integral handle on the tightening screw bolt' so that there is no time lost when the bolt needs to be rotated.

This invention will now be explained by the aid of the accompanying drawings, in which Figure 1 shows one side of av clamp, Fig. 2 is an end view of it, and Fig. 3 shows theother side. In Figs. 1 to 3 the band is relaxed.

Fig. 4 is an end view showing the clamp compressing one article upon another, and Fi 5 is a plan of the parts in Fig. 4.

he clamp is expanded in Fig. 1 with its screw lever projecting outward, the band being ready to be laced around the article or articles to be c amped. The lever is to be swung down asper the arrow, and this has a clamping efiect, the ends of the band being drawn or forced closer to one another.

A is an outer article to bev clamped over an article B. The encircling band C of the clamp is formed of ablank of spring steel, sheet brass, or other suitable material, and is of such length that it makes somewhat less than two turns around article A.

A relatively wide part of the band begins at one end 4, and extends more than a revo- 65 lution around clamped member A and contains a circumferential hole 1, having ends This releases 1' the. band"has a narrow tongue end 6 which is next to the wide portion, part of the band be ng broken away in Fig. 3 to show end 6. The tongue-passes through hole 1,-and its other end- 5 is bifurcated, and has looped limbs 7 riveted atv 5*, to provide eyes or sockets which carry a pivot pin 8. The

- other end of the band is. looped at 9 and riveted at 4 to provide a socket to carry part of a swing member or link 10 the other end -2 and 3. In prolongation of this wide part,

of which is attached to a member 11 which has a screw thread'to receive a screw lever .13, the base of which is revolubly secured to pin 8. p

Link 10 is when desired curved or bent; there could be a combination of links.

Lever 13 has an abutment 15 against pin 8,:wh1ch relatively to its ends is enlarged under the abutment. The lever has an integral wing 14, which enables it to be easily rotated and "which takes a safety position near article A'when the clamp is tight as in Fig; 5.

It will be noted that the spring band conjointly with the link encircles the clamped hose or other article twice, thus increasing the clamping effectiveness of the device.

By swlnging down the lever as per arrow in Fig. 1 its pivot pin becomes located between nut 11 andband end 9; consequently stress is set up which prevents the band returning by spring action to the position of Fig. 1. Theposition of nut 11 can be regulated before such swinging is efiected. This leverage causes a degree of clamping, its extent depending on the nearness of nut 11 to the lever pivot. But when it is desired to force-the ends of the band still closer together, and insure a tighter joint, the screw lever 13 will be rotated to set the nut 11 farther from the pin 8 and thus from hand end 7. 7

- Link 10 and nut' 11 may be integral; the lever may be modified and made operatable by a separate key; washers may be introduced where desirable to reduce friction and provide for wear; bands could be made of wire; they could have a plurality of tongues, and different applications, of the invention may lead to other modifications.

0 release a tightly clamped article, lever 13 should be rotated to move nut 11 closer to pin 8, then the screw bolt should be swung up to, for exam Ie the position of Fig. 1. mi -10 and sets it back into non-clampin position so that the band or rin is then to ex and.

avi described t is invention, what is claimed y Letters Patent is 1. The combination with an encircling spring band having a relatively wide portion and a narrow tongue portion, one end of the latter being adapted to pass through a circumferential aperture in said wide portion, said end having a bifurcation, and a 1pivot pin seated in said bifurcation, of a ever pivotally connected with said pivot pin and having a screw-threaded (portion, a ink pivotally connected at one on with the wide portion of the band, and a screwthreaded member to which the otherend' of the link is connected and with which screwthreaded member the threaded portion of the lever engages in the manner and for the purpose s cified.

2. The com ination with a spring band having a relatively wide portion and a narrow tongue portion havin an end adapted to pass through acircum erential aperture in the wide portion of the band, said end having a bifurcation, of a pivot pin seated in said bifurcation, a lever having a threaded portion. pivotally connected with said pivot pin and adaptedto have a swin 'ng movement relatively to the band, a link aving the form of a bail having a pivotal connection with the end of the wide. portion of the band, and a cylindrical member into the ends of which extend bent ends of the arms of the link so as to provide a pivotal connection therewith and having a transverse screw-threaded opening through which passes the threaded portion of the lever.

In witness whereof I have hereunto set my hand.
